Hogwarts: I graduated before the system came

The others also drew their wands, dispersed, and began to prepare their own magic.

Just when the speedboat circled the island in the middle of the lake for the third time, Dobby finally emerged from the bottom of the lake. The top of the cave was already covered with dark clouds, and the air in the cave began to become dull and cold.

As the speedboat approached, dense swarms of corpses came overwhelming, and everyone felt an unprecedented pressure at this moment.

The moment the speedboat flew onto the shore, everyone seized the opportunity and began to take action...

Dobby activated the magic circle at the bottom of the lake, which was like a fishing net that only allowed people to enter but not exit. Once a corpse entered, it could not get out no matter how hard it struggled.

Bolts of lightning shot out from the clouds. When the lightning struck a corpse, it did not disappear. The electric arc passed from one corpse to another, forming an electric net... Those corpses could not escape and were bound by force.

There was a crackling sound from the end of Dumbledore's wand, and then a giant firebird began to fly around the Inferi. Once an Inferi was touched by the firebird, it would be instantly reduced to ashes...

Douglas felt distressed when he saw this. He quickly took out a small object from his pocket and threw it into the air.

Just as Douglas threw the object in his hand, the lightning in the air suddenly seemed to be attracted by something and hit the object one after another. The lightning spread towards the top of the cave like a fast-growing tree.

The object gradually grew larger, and what came into view was a huge stone tablet with three large characters written on it in an ancient oriental font.

The stone tablet slowly descended towards the lake, and at the same time, the Inferi fell towards the lake with a thud, as if they had been attacked by some kind of gravity magic. Coincidentally, Sirius and Lupin jointly cast a large-scale freezing spell at this time, and the lake surface was slowly covered with a thick layer of ice...

This caused the Inferi to slam hard onto the ice. The lucky ones were frozen, while the unlucky ones were smashed into pieces...

Douglas's mouth twitched when he saw this. What is the most precious thing these days? This pile of black magic products is the most precious. None of them have any idea what waste recycling is.

However, as the stone tablet fell, the ice surface gradually began to break, and those Yin corpses all fell into the water under the suppression of the stone tablet. Until the stone tablet fell to the bottom of the lake, electric arcs suddenly emanated from the stone tablet, like an electric grid, illuminating the entire bottom of the lake with a faint orchid light.

Besides the floating ice cubes and flying firebirds, there are also some scattered arcs of electricity on the lake...

Sirius asked loudly, "What is that, Douglas? Why haven't I heard you mention it?"

The others put away their magic and looked at Douglas with interest.

Just as Douglas was about to make up the origin of the stone tablet, Kreacher's sudden scream attracted everyone's attention.

Seeing that the Inferi at the bottom of the lake had stopped moving and that everyone had put away their magic, Kreacher approached the lake. As soon as he touched the surface of the lake with his hand, he was blown away by the powerful electric current that had not yet dissipated, and hit the rock wall heavily.

However, after taking a glance, several people did not take any action. Only Dobby quickly took out a small porcelain bottle from his bag, carefully poured out a pill, and stuffed it into Kreacher's mouth.

At the same time, he took out a notebook and wrote something on it while observing Kreacher's condition.

Dumbledore saw this scene, then looked at Douglas. Suddenly, he understood why Douglas had so many endless ideas. It was not just because he came from the Muggle world, but more because he was really thinking about research progress...

"The Soul-Calming Monument! That thing is called the Soul-Calming Monument. I made this magical item based on Eastern magic and using stones from Mount Tai in the Eastern Kingdom. Its greatest function is to deal with these dark things. It is most effective against zombies, inferi, ghosts, and the like."

Dumbledore's mouth twitched suddenly, and he suddenly realized that Douglas used this thing here today. If this thing was taken out in Hogwarts, all the ghosts would probably be suppressed under the castle. He even suspected that the thing called the tower where Peeves was imprisoned had a similar function.

Douglas watched the arc at the bottom of the lake gradually weaken and continued:

"Of course, its purpose here isn't just to suppress these Inferi... But I'll keep its other functions a secret for now. Once the arc disappears, we can boldly descend to the bottom of the lake and search for Regulus' remains."

The cave at this time was obviously different from what they saw at the beginning. The sticky darkness seemed to have disappeared under the destruction of the two powerful magics. With the help of the light emitted by the electric arc, they could clearly see the center of the lake.

A smooth rocky island, about the size of an office, with a stone slab and a stone basin with a base, from which the green light emanated.

Chapter 276 Christmas Dinner

The spirit of Christmas is in the air at the Great Hall of Hogwarts School of Witchcraft and Wizardry. The entire hall has been decorated into a magical winter wonderland, and every corner is filled with festive atmosphere.

Twelve Christmas trees filled with silver frost, with gift boxes flying around them. Each box has a ribbon with a question written on it. Only the person who answers the question correctly will receive the gift.

Of course, some Quidditch players tried to catch the flying gifts, but every time they tried to grab them, the gift box would explode into colorful ribbons and shoot out. The sparkling little icicles that were originally hanging quietly on the trees would suddenly shoot out. Each of those icicles could emit a happy spell and hit those who did not follow the rules.

Seeing this scene, the Weasley twins looked at each other and thought of the catalog of the "Compendium of Magical Prop" that Douglas often tempted them with. They remembered that there was a method of making a fake wand on it. They suspected that this icicle might be a gadget made in that way.

Taking advantage of the chaos, the two secretly picked some icicles from the tree, and then hid in the corner to study them secretly, without noticing the interesting look in Professor Flitwick's eyes standing behind the staff seat. Soon there was a burst of crackling sounds in the corner, followed by two bursts of laughter that wanted to stop but couldn't... The laughter of the two people did not stop until the banquet started in the evening. During this period, no matter what magic they used, they could not remove the laughing spell.

Percy said regretfully, "Professor Flitwick and Professor Holmes have jointly cast an additional encryption spell on this Laughing Charm. It's like adding a layer of defensive code to the spell. If you don't know that code, and you try to force the spell to be broken, unless you are more powerful than those two combined, the effect of the Laughing Charm will be delayed..."

"Haha...laughing spell?"

"Set up a magic password to prevent cracking? Haha!"

"Haha... Is the Laughing Charm an advanced magic? Haha."

"Hahaha... maybe they're planning on making their enemies die of laughter."

"Haha...ahem...just like us."

Percy leaned over to the two of them and whispered:

"Let me tell you something: the anti-cracking spell will only activate if you forcibly break the icicle. The boss said this is to protect trade secrets. Theoretically, the more people involved in its creation, the more complex the anti-cracking spell becomes. And no one knows who set the password. In other words, even Professor Flitwick would have a hard time breaking the spell..."

After hearing the news, George and Fred looked at each other with admiration in their eyes. Such a tricky anti-cracking method is quite interesting.

In addition, the Ravenclaw students also imitated the snow monster that Douglas made last Christmas. This Christmas, they made an eagle on their own and placed it in front of the Ravenclaw table. Anyone who walked up to the eagle said, "Merry Christmas."

It would be like the Ravenclaw common room door knocker, asking a question, and if the answer was correct, the eagle would open its mouth and spit out a gift.

Unlike the door knocker, all the questions for this eagle come from students. Each person contributes a gift and can set a question that he or she thinks is the most difficult.

"Who was the Minister of Magic in 1710? What achievements did he make?"

"Who was the Minister of Magic in 1875? What unpleasant decree did he issue?"

“Who invented the dung egg?”

......

"How do you find Professor Flitwick's office from the outside?"

"What's planted in the third row of the third medicinal field in Greenhouse No. 7?"

In short, there are all kinds of questions, and some people even ask questions directly from the test paper.

The Hufflepuff long table was quite interesting. With the prefects taking the lead in applying and Dean Sprout giving special approval, they turned the long table into a small, long kitchen area.

People from all colleges can apply to use these tableware to cook. Of course, they don’t have to worry about the preparation of the dishes. After all, if someone can’t cook during the knife practice in Potions class, they can bring their own small gifts and ask the Hufflepuff who can cook to cook for them, but they have to prepare the dishes themselves.

The only thing to worry about was not getting any weird dishes mixed in. Madam Pomfrey, the school doctor, frowned and worried after seeing this scene. She really didn't want to work overtime on Christmas Eve.

Just when the two colleges were concentrating on doing things, the students of Gryffindor and Slytherin felt a little embarrassed. They didn't expect that the two colleges were so eager and had prepared performances.

When Harry returned to Hogwarts, he happened to see a chili dessert made by Ginny. Harry ate it with tears in his eyes.

Then Harry secretly called Ron and Hermione to a corner of the castle and told them some of the things that happened today. Of course, he only picked out some of the things that could be said. As for the parts that could not be said, he told them honestly that he could not tell them for the time being.

Ron felt a little unhappy when he heard that Harry was still hiding something from him. Hermione was more embarrassed. After all, she too was hiding a secret from these two.

When Hermione heard Harry say that Sirius's home was in London, nestled among Muggle buildings, she found it quite interesting. After all, the wizards she had met and read about in books either lived far from Muggles or integrated into their lives, living in the same houses as them. But she had never heard of a house hidden among Muggle houses like this.

Then she thought about it and it made perfect sense. After all, the Black family was an ancient pure-blood family. At least she had never seen in any book that a pure-blood family would expose the address of their home to the outside world.

As they were chatting, they encountered the Gryffindor ghost, Nick, who was almost headless. When asking people to say hello, Nick casually asked, "Why don't I see that person?"

Almost everyone in Hogwarts knew that the person in the ghost's mouth must be Professor Holmes.

Harry said casually, "He's out on some business with Professor Lupin and Headmaster Dumbledore. He might not be back today! Do you have anything to do with him?"

As soon as Harry finished speaking, Nick threw his nearly-lost head all over the place.

"No, no, no, I'm just asking casually. I have something else to do, so I'll leave first. Merry Christmas, everyone, and have fun."

Just ten minutes after Nearly Headless Nick left, the ghosts of Hogwarts told each other that they would attend the Christmas dinner tonight. This time, even Peeves and his friends were not excluded and were notified.

The ghosts hurried to prepare for the show. Peeves even thoughtfully wrapped up his moldy bread and peanuts in attractive packaging. He even sneaked into the kitchen and, while the house-elves were busy, secretly stole half a bucket of Douglas's stinky tofu juice. He then bottled it in many small bottles and thoughtfully tied them with bows.

George and Fred were also very happy when they heard that Peeves would be attending the Christmas dinner. They specially asked the house-elves to make a small cake in the shape of Sherlock Holmes's pagoda.

Now many students at Hogwarts like this. There is a pagoda built by Professor Holmes. Especially when someone is bullied by Peeves, as long as they run near the pagoda, Peeves will not dare to come near.

There were even some clever people who, when they first saw that Peeves was afraid of the pagoda, made some models of the pagoda, and whenever Peeves appeared, they would reveal the pagoda.

At first Peeves was a little scared, but later he found out that the pagoda was not made by that person at all, so he took revenge on those students crazily.

Chapter 277 Seeking Light in the Darkness and Selflessly Dedicating Ourselves to Justice

cave.

After controlling all the corpses, the electricity in the lake gradually dissipated. After ensuring that there were no other living creatures in the lake, several people crossed the lake and came to the island in the middle of the lake.

After stepping onto the island in the middle of the lake, a stone basin similar to a meditation bowl emitted a faint blue light, with a base underneath, like a lamp.

They actually stood side by side in front of the stone basin and looked inside. The basin was full of emerald green liquid, emitting a sparkling phosphorescent light.

At this time, Kreacher rushed into the lake again and groped his way forward based on the location he remembered.

As for whether Regulus has turned into an Inferi, no one is worried at all. The formation of an Inferi requires a dark wizard to summon and manipulate it through black magic, and it is obvious that Regulus does not have this condition.

Just as Kreacher jumped into the water, Sirius followed suit, but he immediately surfaced within a minute.

"The Luminous Charm can't be used down there. There seems to be a force in this lake that restricts the Luminous Charm."

Douglas snapped his fingers casually, and a clear spring appeared out of thin air and flowed towards the ground, but when it approached the ground, the spring suddenly disappeared out of thin air.

"It's not just the lake. There are also some restrictions on this island in the middle of the lake. For example, you can't drink water here. And the measures taken in the lake, I think, are mostly aimed at the Inferi. Voldemort wants to provide them with a suitable living environment. And the magic that has been able to last so long and hasn't been destroyed by the lightning just now is probably only potions... Is he good in Potions?"

Halfway through his words, Douglas looked at Dumbledore and asked in confusion. He found that Voldemort really loved using potions.

Dumbledore, who was detecting the liquid in the basin, was also choked by Douglas's sudden question.

"Yes, Tom was an excellent Potions student, and you can hardly imagine how much my old colleague Horace Slughorn liked him.

Oh, by the way, Horace was the previous Head of Slytherin and Professor of Potions. Last Christmas, after your new book launch, he wrote to me, saying that he admired you very much and asked if I could invite you to dinner. I forgot about this..."

"..."

After seeing Lupin summon a ball of fire to illuminate Sirius and Kreacher in the lake, Douglas stopped interfering in the matter and continued to study the potion.

He put his hand in...

"Boss, no, don't touch it, let Dobby do it..."

"Hush! Non-Newtonian fluid?"

Dumbledore said puzzledly, "What?"

Dobby proudly explained:

"Non-Newtonian fluids are fluids in the Muggle world that don't conform to the laws of motion of Newtonian fluids. Their viscosity (resistance) isn't constant, but rather varies with stress. Simply put, the viscosity of a non-Newtonian fluid depends on the type and intensity of stress applied...

Newton is an alchemist in the Muggle world, of course Muggles don’t call him that…”

Dumbledore smiled and said, "Thank you, Dobby... I didn't expect you to know so much about Muggles."

Douglas shook his head again and said, "No, my hands can't touch the liquid at all. They are directly blocked by the air..."

Then Douglas took out the magic radar again...

When Dumbledore saw the magic radar, his first reaction was to look at the lake behind him. This thing should be able to find people faster, right?

Soon the radar interface displayed a schematic diagram of the entire island in the middle of the lake, with lines of various colors cross-connected.

It is obvious that Voldemort used magic to connect the entire island in the middle of the lake into a whole.

Then he put away the magic radar and said, "I won't do this here. I think Professor Snape will be very interested in this, so I'll leave it to him. This potion is nothing special. It just makes people weaker..."

Dumbledore nodded and said:

"I think Tom doesn't want anyone who lands on this island to die immediately. He'll keep them alive for a while so he can figure out how they got through his defenses, and more importantly, why they came here. After all, in his plan, he believes he's the only one who knows about the existence of Horcruxes."

Douglas sneered, "It's a pity that he ignored the magic of the house-elf, which allowed Regulus to find a loophole. If Regulus had come in through the normal means at that time, he would have discovered that his Horcrux was missing very quickly."

While the two were discussing, Kreacher and Sirius emerged from the lake at the same time, their faces covered in water, it was hard to tell whether it was water or tears. Sirius was holding a corpse in his arms...

Dumbledore and Douglas looked solemnly at the young corpse. Perhaps it was the special effect of the lake water, he still retained his appearance when he was alive.

His black hair was covered in mud, dripping down with the lake water. A mocking smile still hung on his pale face. He was thin, and his clothes were already tattered. Clearing away the mud from his body revealed his scarred skin, and using a spell to untie his tightly clenched fist, he revealed a Black family crest...

Kreacher knelt beside Regulus, banging his head hard on the stone, but did not try to stop him at this time...

Sirius silently cleaned the mud off his brother bit by bit.

The others watched the two of them quietly. After Sirius had cleaned up Regulus, Dumbledore waved his wand and a Slytherin flag was summoned, gently covering Regulus...

Now that they had found Regulus, they did not stay in the cave. Douglas placed Regulus' remains in the sarcophagus. This action made Kreacher look at him with gratitude again.

Back in the entrance hall, Douglas said, "Sirius, I suggest that Regulus be buried here. What do you think? He won't be alone. There will be more victims who came to keep him company, and future generations will be able to admire his deeds."

Sirius nodded, his eyes still red as he said:

"Well, I don't want him to be contaminated by the Black family's dirty ancestral tomb. He is a good boy... Shut up."

Sirius's last words directly interrupted Kreacher's rebuttal.
